Due to the world-wide microprocessor shortage, many electronic parts supplied to the GM Dealer network by GM's Authorized Electronic Service Centers are on national backorder.  We recommend you continue to place your orders with Specmo so that your order can be filled on a first come, first served basis when the part(s) become available.  Thank you for your patience in this unprecedented situation.
